When a person dies, he moves from this world to another realm, and his soul does not come back to his family and they do not feel anything of him. What is mentioned about the soul coming back for forty days is a myth that has no foundation. Similarly the dead person does not know anything about the circumstances of his family, because he is absent from them, in a state of bliss or torment. But Allaah may inform some of the dead of some of the circumstances of their families, but this is not necessarily so. There are some reports, which cannot be relied upon, that say that the deceased may know something about his familys circumstances.
